Deoxynivalenol (DON; also called vomitoxin)

DON is proving to be a problem this year in southern Illinois. There are several reports that DON levels are so high that loads are being penalized with price reductions in some counties. In some of these cases, high DON is associated with areas that also had significant head scab (Fusarium head blight caused by Fusarium graminearum). However, some cases of high DON levels are occurring despite lack of visual symptoms in the wheat and good test weights and average yields.
